8、lt in hazardous radiation exposure. WARNING!WARNING! 1. Service should only be performed by qualified personnel. 2. This equipment has been designed and manufactured to meet international safety standards; it is the legal responsibility of the repairer to ensure that these safety standards are maint

9、ained. 3. Any repairs must be made in accordance with the relevant safety standards. 4. It is essential that safety and EMC critical components are replaced with Cambridge Azur approved parts only. CLASS 1 LASER PRODUCT NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the

10、optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in

11、 the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concerated so as to be focused on the disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the

12、laser diode emission, observe from more than 30cm away from the objective lens. 4 5 Cambridge Audio Azur 640C V2 CD Player AP175163 Front Panel PCB Schematic SW1 PLAY/PAUSE SW2 STOP SW3 OPEN/CLOSE 1 2 CN1 CONN-H2 SEG11 16 SEG10 15 SEG9 14 SEG8 13 SEG7 12 SEG6 11 SEG5 10 SEG4 9 SEG3 8 SEG2 7 SEG1 6 S
